In Tap! Dig! Museum! you build the skeletons piece by piece so it might still be able to help you with ideas for "bits" even if you want to avoid being too influenced by the full skeletons. I really appreciate that you don't want to be influenced though. Once you're done with your museum updates I'd recommend playing the game, however, as it is very charming.
(As an aside, the museum updates are what finally convinced me I had to buy this pack, even though I will probably never use it, because I just love looking at your art so much, and how hard you work to make original art, and I wanted to chip in a little bit that I could afford.)
